i APPARATUS FOR SUBMARINE TELEGRAPHY AND SIGNALING.

Specification of Letters Patent. Patented Aug. 20, 1912.

- Application filed December 3, 1910. Serial No. 595,500.

marine Telegraphy and Signaling, of which the following is a specification.

Our invention relates to apparatus for submarine telegraphy and signaling, and more especially to such apparatus when the transmission is by means of sound waves,

the impulses of which pass through water from the sending point tothe receiving point.

As the invention will be specifically illustrated and described herein, it is shown applied to the production of audible sound waves in, and their transmission from, ships, although obviously the principles-would be applicable to other and analogous situations. The present improvement implies a proper receiving apparatus, but as the details thereof do not per se form a part of this invention, the disclosure hereof is-restricted to the sending apparatus.

The most important requirements for signaling and 'telegraphin by means of sound waves transmitted un or water, are: that the transmitting device should be arranged in the interior of the ship or of some other body in the water; further that the sound producing device should be suitable for giving notes continuously, for instance for Morse signs; that the sound producing device should be suitable for producing high notes, more especially musical notes of high pitch, which are particularly well transmitted in water; and further that it should be possible to produce notes of different pitch. These requirements are only partly and not thoroughly complied with by the sound transmitting devices for submarine signaling at present known, and such known devices are also very complicated, whereas an apparatus constrlu-tcd under the principles of the present invention may be extremely simple.

This invention relates to a transmitting device which fully complies with the above rcquirei'ncnts.

In substance the present invention consists in a submarine telcgraphiug and signaling system wherein is employed a vibratory member for producing (by its own vibrations) an audible note or tone, together with a sounding board (for example, the shell of a ship) which is located in the water for sending out the vibrations into the water, the apparatus being so arranged that the tone producing mechanism is located out of contact with the water, but directly connccted with the sounding board. The side of a steel ship is peculiarly adaptable to this invention since it constitutes a plate or shell immersed at one surface in contact with open water, and out of contact with such water at its other surface,.enabling it to be combined with a member adapted to sonorously vibrate, the latter being located'at, and operatively' connected with, the nonimmersed side of the shell or plate for'causing vibrations in the latter. While various forms of note producingmechanism could be employed, the present invention is illustrated with such mechanism consisting of a longitudinally vibratable member connected to the sounding board and suitably actuated. t

Our experiments have shown that for'attainingthe purposes above stated strings stretched in the interior of the ship or other floating body between the walls of the same and vibrated in a suitable manner can be advantageously used, as vibration producing systems. When such a device is used, the ship or other body acts as a stringed instrument which, like musical instruments such as piano, violin, etc, forms an excellent sub' marine source of audible signals, etc.

\Ve will first describe specific embodiments showing the general principles of the present invention in a more or less' diagranuuatic way, but amply full to enable those acquainted with the artto readily construct and apply the same. I

In the accompanying drawings forming a part hereof, Figure 1 indicates asupposed cross-section of a floating ship or other ves sel with all unnecessary parts 0mitted,-and with the present invention shown embodied therein in a simple form. Fig. 2 in a similar view shows another form of einbodiinentof this invention. Fig. 3 in a part cross-section of a ship shows the invention when "a plurality of note producing devices 1s employed.

Similar letters of reference designate corresponding parts in the several figures of the drawings;

A construction according to this invention isdiagrammatically illustrated by way of 'examplein Fig. l of the accompanying .drawings Between the lateral ivallsof the ships body'I-I shownin cross-section, is

' is for instance excited in the longitudinal directionby the rotation of a friction wheel 1- covered by cloth or some other suitable material. The sound continues as long as the wheel is rotating or the string touched In that Way Morse signals can be produced.

The number of strings can be of course increased as desired. The stretching of the same "can be effected in the interior of the ship, or also from the outside above the water line between any desired points. By using several strings tuned to different" pitches, notes of various pitches can be produced, which enables easily intelligible musical signals to be given. Besides ships, such a device can'also be provided on any other floating bodies oron bodies immersed in water.

' Experiments have shown that other excellent, sound producers are'rods fixed in the center, which can be easily excited owing to their both ends being free- An' example of such a device is diagrammatically shown in Fig. 2, a fixing device 6 of an desired kind, secured to the ships body holding in the center a bar or rod 25 which can be given longitudinal vibrations by means of a friction wheel. r. A more perfect transmission to theships body could also be effected by means of cords, wires or the like 8 connecting the free ends of the vibrating rods to the ships body or to other floating bodies.

In Fig. l the, string 8 andin Fig. 2 the rod or bar If is in effect a vibratory element extending between and connected at opposite ends to the walls of the hollow floating body or vessel. whereby when the element is set in vibration. such vibrations are transmittcd to the walls of the hollow body or vessel and in turn trmislnittcd to 'thebody of water in which the vessel is located.

The exciting device can be operated either by hand or by means of suitable mechanism. It is obvious that exciting devices ofany other desired kind, for instance reciprocating plucking devices can be used.

In Fig. 3 the system embodies a sending apparatus including the ships shellas a. sounding board located in the water for sending out vibrations into the water, t0- gctherwith means consisting of a plurality of vibratory 'members, 1;, v '0 'v*, eaol1 connected directly with the sounding board but located out of contact with the water, the several vibratory elementsbei-ng adapted or tuned for producing audible-tonesof different pitches, and having means for vi brating th'emQ Thus the four vibratory elements are shown of grad uated lengths, which would give them graduated pitches. ,E'aeh of them may have at its inner end a threaded piece wpassing through afixed apertured piece 10 on an inclined standifrd- W, and a nut 'w engaging the threadsof piece 'w for tightening the member.

.Fo'r vibrating these'veral members, a single friction wheel zamay'be employedmounted on a slidable crosshead w'having means y for clamping 'it in the desired position on I the guide rods 2.

By detaching one of the vibratory cle ments as v, the friction wheel r-may there upon be shifted into contact with the 'suceeeding member '0", and itniay be similarly shifted to any one "of the elements.
